The Ajax HomeSiren is designed for indoor use and comes with a siren, mounting kit, external LED connector, and instructions. This wireless siren is significantly smaller than its outdoor counterpart, offering enhanced concealment to thwart intruders' attempts at disabling it. It features a tamper protection mechanism, a standard in Ajax Systems' product line, which sends a notification to the user's phone if there's an attempt to dismantle the siren, regardless of the system's armed status. To activate the siren, the user should rotate the rear panel counterclockwise to detach it, open the panel, and press the power button until it clicks, indicated by the LED blinking green in the upper right corner.
